As SAP has announced that it will discontinue support for SAP Process Integration (PI) and Process Orchestration (PO) after 2027, organizations relying on these systems must plan for migration to SAP Integration Suite (SAP CPI). This transition involves careful consideration and planning to ensure a smooth transfer of data and processes.
SAP PI/PO, a widely used middleware platform, connects SAP and non-SAP systems, facilitating integration across diverse applications. However, with SAP's future discontinuation of support, migrating to SAP CPI has become crucial for maintaining operational continuity and leveraging advanced features. The migration process involves several key steps, starting with assessing the current integration environment to identify which integrations need to be moved.
The migration begins with evaluating your existing integrations and creating a comprehensive plan. This plan should outline a migration schedule, allocate necessary resources, and define the specific steps required for a successful transition. SAP offers tools like the Migration Cockpit, which helps identify and migrate integrations from PI/PO to CPI. Additionally, third-party tools and consultants can assist in navigating the complexities of migration.
One of the primary tools for this transition is the Migration Tool within SAP Cloud Integration. This tool allows for the automated migration of integration artifacts from SAP PI/PO to SAP CPI. It includes a migration assessment feature that estimates the technical effort required and helps in assessing how different integration scenarios can be transferred. This assessment involves extracting data from the existing SAP PI/PO system, which can be complex but essential for a smooth migration.
The migration to SAP CPI offers several benefits. It provides better performance and scalability, reducing costs and offering access to new features. Increased flexibility and enhanced security are also significant advantages. However, the migration process presents challenges, including the complexity of the transfer, the need for staff training on the new platform, and the potential risk of data loss or corruption.
To establish a connection between SAP PI/PO and the Migration Tool, you must first enable the Migration Assessment feature in the SAP BTP console and assign the necessary access rights. Ensure that the SAP Destination service can access required API endpoints for data extraction. In the Cloud Connector, configure a new HTTP destination with the backend type set to SAP Process Integration, including the host and port address.
Once the connection is established, navigate to the Transition Assessment application settings. Add your SAP Process Orchestration system, enter the system name, description, and integrated folder information, including the URL and technical user credentials. The user must have specific roles assigned for the connection to be successful. After setting up the connection, you can test its functionality.
The migration tool aims to automate as much of the process as possible, achieving up to 60-70% time savings. The tool analyzes existing integration scenarios and creates corresponding integration flows in SAP Integration Suite based on predefined templates. This process involves selecting the SAP Process Orchestration system, creating a connection, and migrating Integration Configuration Objects (ICOs). Filtering ICOs, selecting migration templates, and previewing integration flows are key steps in the process.
Post-migration, integration flows require configuration adjustments. For instance, setting the proxy to "On-Premise" in the receiver SOAP adapter and validating XSLT mappings are essential tasks. Ensuring that security artifacts are correctly defined and deploying required components are critical for successful integration flow operation.
In conclusion, migrating from SAP PI/PO to SAP CPI is a complex yet beneficial endeavor. By carefully planning and executing the migration, organizations can leverage the advanced features of SAP CPI, ensuring improved performance, scalability, and future-proofing their integration capabilities.
